PATENT FRANK S. JONES, OE PHILADELPHIA, PENNSYLVANIA.

POWER DRIVING B'IECHANISM.

Application filed December 28, 1920. Serial No. 433,727.

To all whom it may concern:

Be it known that I, FRANK S. Jonns, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Power Driving Mechanism, of which the following is a specification.

One object of my present invention is to provide an improved power driving mechanism for use in connection with the feed mechanism of large slotters such as my im proved slotting machine forming a part of my co-pending application for U. S. patent, Serial No. 378,146. For example the improved mechanism of my present invention can be used with particular advantage for operating the work table and carriage of said latter slotting machine by power derived from the machine so that a workman can quickly move said table into the proper position to set up the work ready for the out.

Another object of my present invention is to so construct my improved mechanism that it can be readily operated from either side of the base of the machine so that a workman can easily control it from either side of the base of the machine whereby the workman is not compelled to walk from one side of the machine to the other in order to start or stop the mechanism. 7

, Another object is to make my invention in a comparatively simple and durable manner.

I These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a fragmentary side elevation showing my improved power driving mechanism connected to a slotting machine of the character described and illustrated in my above mentioned co-pending application for patent,

Figure 2 is a fragmentary transverse sectional elevation illustrating the lever control for the mechanism of my present invention,

Figure 3 is a section taken on the line 33 of Figure 5, illustrating my present invention and drawn on a larger scale than the illustration of said present invention in Figure 1,

Figure 4 is a section taken on the line -et of Figure 5,

Figure 5 is a section taken on the line 55 of Figure 3, and

Figure 6 is a section taken on the line 6-6 of Figure Referring to the drawings, 7 represents a large slotting machine such as described in my above mentioned co-pending application for patent and which includes a shaft 8 which when rotated effects the rotation of the work table 9 and the transverse movement of a carriage 10 which supports the work table 9. The above mentioned elements do not in themselves form a part of my present invention since they are covered in my above mentioned oo-pending application and receive operative power during the slotting action of the machine due to the movement of a link 11 which imparts motion to a ratchet wheel 12 through the medium of a pawl 13 on said link 11. It is necessary however in order to set up the work with respect to the cutting parts of the slo'tter to move the carriage and work table so as to bring the work in proper relative position with respect to the cutting elements and my improved mechanism of my present invention is adapted to rotate, by power derived from the machine, the shaft 8 in order that the carriage and work table can be quickly moved into a desired position.

My present invention includes a casing let which has a bracket extension 15, as shown in Figures 5 and 6, for attachment to the base 16 of the slotting machine. This casing at one end provides a bearing 17 for a hub 18 of a gear wheel 19; said gea wheel being positioned within the casing 14 adjacent one end thereof. The hub 18 is rigidly'secured to one end of the shaft 8 in the present instance by a pin 20. A second gear wheel 21 is mounted within the casing 14 adjacent the opposite end and is opposed to the gear wheel 19. The gear wheel 21 has a hub 22 mounted in a bearing 23 provided by the casing 14 opposite the bearing 17. A primary shaft 24lhas a bearing in the hubs 18 and 22 and is freely rotatable with respect thereto. This primary shaft has a portion which extends outside of the easing and to which is attached a pulley 25; said pulley being operatively connected by a belt 26 with the motor 27 which is also used for the purpose of operating other parts of the slotting.- machine. -;,;The ;gear' Wheel 19 has an inwardly tapering cavity providing a frusto-conical friction clutch surface 28 and the gear-wheelfll hasl acavi y providing a frusto-conical friction clutch surface 29. A clutch collar-'30 is slidably keyed to the primary shaft 24 andhas opposed clutch portions 31 and'32 which are intermediate fpijnion V mesheswith a secondary. il'itfirifn'diate pin ion 36- Which is secured to the shaft 3t a'nd the secondary intermediate pinion meshes with the gear heel 19.. clutch operating lever ,37 is;pi;v013ed at 381m the-leas ng l'fL and has, a portion 39 which-engag s? 1 5 113 groove in the clutch collar 30; The clutch lever, 37 v has anarm} Whi e, [projects] upevardly out of, the casing 14 and is connected by ,a link .42, with the, lower 6nd,. of e a ha nd lever 4:3; said .handelever' being, ,se curedito' a shaft ii which extends transverselyfrorn oneiside .of the machine tofthe other and a itsaopp e end this. .haft: s hasjanr handelever 4:3 v sec e 't erete ,Thu by moving either ofj the haIid-lev'ers 43f; or 413 thevlink 421 can be rn' edot iswingathe ,clutoh leYenB'Z on its;pivot 38' so astojslide theolutchwcolla'r 3min opposite directions alongithe prima y s ft 2a..;,-- r. h In the operation of my improvedmechanism, consideri g t t the: v Shaf .2 i .10- tating. constantly ,in one direction, the clutch collar is'moved into driylng engagementwith the Wheel .19, 'theshaftfi'yvi be driven in the direction of the shaft the w b e-an c r iage. will; be: mo ed ina directiondepe'ndent uponsaid direction ofmovement of th'esh'aft8 If,on' th e'otl'1er hand, itheclutch collar 39 is moved longitudinally .in anopposite direction S0'I & S ,to ,en- :.gg;age. th he l 21, the.
